blank beini bransversely located"on the ribs,

the blanks ein held in position by means of the posts n an a vertieally-ad'ustable gate o, well knownln machines of t "s dass. A feeding device for these blanks has a sliding movement beneath the pile of blanks and is Wha is known as the shovel-feed and consists in a earrier or slide p, hav1'ng a shoulder g thereon movable in slots in the table between the ribs m, said shoulder g extending just above the level of the table to engage with the rear edge of the blank and move the same out be'neath the gate 0 into position to be engaged by the feeding devices (shown in Figs. 3 and 16 partieularly) and which have a reciproeating sliding movement reetangularly of the initial movement -of the blank above referred to, the folding-box of the maohine being in position to receive the blank whieh is loeated therein by said referred-to rectangularly-moving art 0f the feeding meehanism. Theblan as a whole will be indicated herein by A.

The driving mecbanism of ehe machi-ne consists of a shaft r, rotated by a driving-pulley s. On thisshaft' is located a number of cams, 130 be described farther on, whereby the blanks are moved into osition over the folding-box, and whereby t e folding-wings for the end flaps and the folding-fingers for turning in the corner-flaps of the blank are aetuated, and whereby ehe plunger t has imparted thereto vertical movements, and whereby the loeking-ton ues of the blank are raised, as shown in atingwith this shaft r is another shaft v, parallel therewith and having oams thereon, whose function Will be hereinafter described, these two shafts being rotated in opposite dir'ections by gear eonneetions eonsisting of the gear x on the shaft r and the gear y on the shaft v, the position of which is elearly shown in Figs. 2 and 3. Both of these shafts are located beneath the table k and parallel to the length thereof. Also beneath the table is a short shaft 3, rota'tively conneeted with the shaft r by the beveled gears 4. The fi1nction of the shaft 3 is to withdraw a blank from beneath the pile of blanks A and lo.cate i t, as described, in line with the foldingbox, as shown in Fig. 6, a blank being shown in this position in dotted lines in said Fig. 3.

The withdrawal of the blank from beneath the pile of blanks is efieeted, as stated, by the sliding carrier p, which by a conneetihg-rod 5 has reci rocating movement imparted theretoby t e ivotal eonnection of one end thereof 120 a dis 6 on the shaft 3. (See Figs. 1 and 3.)

The feeding fingers whieh engage the blanks are indlcated by 7, and they are sups ported, as shown in Fig. 3, a1: opposite endof' a long sleeve 8, slidably supported on a rod 9, parallel with the side 01 the folding-box, and connected to this sleeve er forming part ig. 15, and coper thereof is a rearwardly-extending arm 10, the

end of which is loeated over the periphery of the disk 6, on whi'chthere is a cam projection 12, whereby this arm is moved in a vertical laue.

Parallel w1'th and in the same plane as tbe rod 9 is a second rod 13, a portion 14 of Which is reduced in diameter, as shown in Figs. 3 and 16, whieh rod passes loosely through the arm 10, the reduced ortion 14 of the rod being so loeated that W en ehe feeding-fingers 7 are in the position shown in Fig. 3, at which time the eam 12 depresses the forward ends of said fingers, the latter and the arm 10 may have a Certain degree of roeking movement on the rod 9, but after the blank has been engaged by alle fingers by the foreing 0f the buttons 15 0n the end of the latter down throu h the euts made in the blank so rovide t e ton ues h the sleeve 8 is move toward ehe fol ing-box, and as soon as the normal diameter of the rod 13 is reached tl1is sleeve becomes non-rotatable on the rod 9 during the rast of its movement, and, furthennore, when that part of the rod 13 having a normal diameter is reached it tends to elevate the forward end of tl1e fingers 7, and thereby elevate the blank slightl That bne of the fingers 7 whic is nearest the f0lding-box has a reetangularl -dis osed portion 7f, which. extends toward tl fo dingbox and serves 120 push out of the latter a completed box.

The slidin movement 0f the feeding-finers 7 towar and from the folding-box 1s ef- %ected by rneans of an arm 16, supported on a vertically-disposed shaft 17, which extends through the table and has seci1red to its lower end the segmental gear 18, whicl1 meshes with a sliding rack 19 and which has irnparted thereto reciprocating movements in opposite direetions y means 0f the cams 20 and 21, loeaoed, respectively, on alle shafts 1 and v, (see Figs. 1 and 3,) which rotate, as stated, in opposite di1ections, dependin arms 22 being secured to the under side 0 the raek at each end thereof, as seen clearly in said Fig. 1, said eams. contaetinp arms 22 als proper intervals 130 roduce suc 1 reeiprocat1ng movements of t e rack.

When the blank A is movml to a position over the folding-box, the lunger t ls elevated suflic iently-to allow the lank to pass under it, as shown in Fig. 1, and as soon as the blank is in position the plunger, which is gravity-actuated, is allowed to drop by the passing out of the plunger-cam 23 from under the post 24, With which the plun er is eonneeted by an arm 25, as shown in t 1e various views from Figs. 4 to 15, inclusive.

The bottom of the folding-box is -the surface 0f the table k, and the tw0 Ion 'tudinal sides of the box consist 0f the vertica I'ibs 26. Thus when the plunger falls the side and corner flaps a and c are turned up at ri9rht an- IOC IIO

sition shown in Fig. throughthe momentum of 1ahe'se paros of the mac hine when in operation.

Reference has beenmade 110 the levers 56, Which bend up the locking-tonues g, as shown in Fig. 15, and this movement takes place as follows: These levers are sup orted in slots cut in the edge of a bar 59, W 'ch is carriecl 0n the end0f a-post 60, which extends through a boss 61 on the under side- 0f the table, and the normal osition of this bar and said le ver is shown 111 Fig. 7. Extending through ehe dpos1: 60 is a pin 62, which supports one en 0f a spiral s}g)ring63, the upper end*of which bears 0n a s 61, the lower end 0f this b0ss being slotted, as

a1: 64,130 permit verticalplay 1:0 the pin 62,-

' and whereby the post 60 may be prevented from rotating. A cam 66 on the' shaf.t 1" ab the pro er time swings against. the under side-of t e lower end 0f the p0st 60 and moves i0 and 1:he levers 56 toward 'the table, the l0ng arme o'f these leVers extending through holes in the table. The. shor1: upturned anne- 0f these levers eome against the under side of the table, and as the lohg arme m0ve up against the t0ngues g this contaet 0f the shor1;

When the cam 66 moves out fr0m under said p0st 60, the s ring 63 forces' the latter and the bar 59 ownward, and the long arms.0f the levers 56 Stflking against the beveled edge 0f the holes in the table are swung back again 120 the position shown in Fig. 7, aided by 1;he springs 67.
